Hi Rami,

I see no problem with the vif-driver getting information returned from
Quantum per-se.  In fact, tr3buchet is reworking the nova/quantum
integration code and as a result some values from Quantum (e.g., allocated
MAC + IP address) will most definitely be passed to the vif-driver.

However, I do want to make sure that the vif-plugging driver stays "thin"
and focused primarily on connecting the vNIC to the switch.
